Abstract
In the case of oblique incidence (when the incident and the scattered beams are not perpendicular) it is shown that if the electric vector is parallel to the scattering plane the Raman spectra have a ‘‘complex’’ polarization—the Raman intensities are obtained after adding the scattered amplitudes and squaring their sum. However, if the samples are uniaxially oriented around a Z axis, simplification occurs, due to the average over the φ rotation angle (and if necessary over ψ, which is the rotation around the z axis of the molecule) and now it is the intensities which can be added.Keywords
